EVMPersistentSigner

Defined in: atomiq-chain-evm/src/evm/wallet/EVMPersistentSigner.ts:25

A robust EVM signer implementation with internal nonce management, automatic rebroadcasting and fee bumping. Uses Node.js fs to persist transaction data across restarts, so it is intended for backend runtimes.

getReproducibleEntropyMessage()

static getReproducibleEntropyMessage(appName): string;

Defined in: atomiq-chain-evm/src/evm/wallet/EVMSigner.ts:28

Returns a static message, which should be signed by the EVM wallets to generate reproducible entropy. Works when wallets use signing with deterministic nonce, such that signature over the same message always yields the same signature (same entropy).

Parameters

Parameter	Type	Description
appName	string	Application name to differentiate reproducible entropy generated across different apps

Returns

string
